A multitasking terminal for
Claude Code

Run multiple Claude Code sessions in parallel, let agents collaborate with each other while working in their own isolated environments, track what every agent is doing at a glance, and respond to approvals and questions — without getting lost in tabs and windows. Built for humans who multitask with AI.

conduct an orchestra of agents

gems & shards

Group work into gems, each with its own terminal sessions. The Crystal Rail keeps every project one click away — even with dozens of shards running.

keep agents on task

The more agents you run, the harder it is to keep up. Crystl's approval panels, notifications, and session colors let you spot what needs attention so nothing stalls.

parallel without conflicts

Run multiple Claude instances on the same repo using isolated shards. Each gets its own git worktree and branch — no stepping on each other.

conversation history

Every session is preserved. Scroll back through what Claude did, what was approved, and the full context of each conversation — across all your gems.

session restore

Claude sessions autosave and restore when you restart Crystl — pick up right where you left off. Guild members get session restore in formations too.

remote development

SSH into any machine and keep every Crystl feature working. Approval panels, file drag-and-drop, and click-to-open all flow through the tunnel automatically.

starter bundles

New gems launch with CLAUDE.md, rules, skills, and MCP config — all pre-configured from your bundle library.

project optimizer

Scan your project for gaps in agent configuration — missing files, incomplete docs, oversized code — and fix each one with a single click.

skills library

Browse and import slash commands that teach Claude new tricks — code review, testing, deployment, and more.

Crystl Quest

Assemble a party of specialized agents. Each brings unique skills, coordinates in shared chat, and executes in parallel — without stepping on each other's toes.

Frequently asked questions

Does Crystl only work with Claude Code?
Crystl is built around Claude Code, but it also has early support for OpenAI Codex. That said, features like approval panels and notifications rely on hooks that Claude Code provides — Codex doesn't support hooks yet, so those features aren't available for Codex sessions.
Can I use Crystl for regular terminal work?
Yes. Every shard is a full terminal session. You can use Crystl as your daily terminal for any command-line work — git, npm, docker, ssh, whatever you need. The AI-specific features are there when you want them.
What is the CLAUDE.md manager?
Crystl lets you store and name different CLAUDE.md starter files. When you open a project, you can insert the right starter file into the directory — useful if you maintain different instruction sets for different types of work.
Is Crystl free?
The free plan includes 5 gems, 5 shards per gem, isolated shards, MCP server config, API key storage, split view, conversation history, session autosave & restore, Metal GPU rendering, and 5 Facet Inserts. The Guild plan ($85/year) adds unlimited gems, shards, and Facet Inserts, plus the Prompt Library integration, formations (with session restore), and priority support.
Does Crystl work on Linux or Windows?
Crystl is macOS only. It's a native Swift app built on Metal for GPU-accelerated rendering, and it uses macOS-specific features like the Keychain for secure API key storage.
